Diagnostic Accuracy of Point-of-care Ultrasonography for Confirming Endotracheal Tube Placement in Adults: An Updated Systematic Review and Meta-analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Point-of-care ultrasonography (POCUS) is increasingly used to confirm endotracheal tube (ETT) placement; however, its overall diagnostic accuracy and speed compared with standard methods in adult emergency and critical care settings remain uncertain. Methods: We conducted a systematic review and meta-analysis of observational studies through May 2025 that evaluated POCUS for confirming ETT placement in adults (≥18 years) in emergency departments (EDs) and intensive care units (ICUs). Results: Thirty studies met the inclusion criteria. Point-of-care ultrasonography achieved a pooled sensitivity of 0.91 and a specificity of 0.98. The area under the curve (AUC) was 0.96 [95% confidence interval (CI): 0.88-1.00]. The mean time-to-confirmation was 19.62 seconds for POCUS vs 22.46 seconds for standard methods; however, this finding should be interpreted with caution due to extreme heterogeneity ( Conclusion: Point-of-care ultrasonography is a highly accurate, rapid, and reliable method for confirming ETT placement in adult ED and ICU settings. It demonstrates diagnostic performance comparable to previously reported capnography performance and provides unique advantages as an adjunctive tool, especially in scenarios where capnography may be unreliable.
